On gamma-ray emission from pulsar magnetosphere
(BRAC University, 2007)
Pulsars, a class of rotating neutron stars, are one of the most interesting objects of nature. Although most pulsars have been detected in the radio range, a handful of them are active in gamma rays. In recent years, ...
On Terahertz laser pulse propagation in negative index metamaterials
(BRAC University, 2013)
The nonlinear propagation of a terahertz laser pulse propagation in the resonant region of a negative index meta-material is investigated. The resonant frequency of a split ring resonator (SRR), comprosing the negative ...
Data acquisition and study of He spectrum under electric and magnetic fields
(BRAC University, 2013)
Data acquisition system for the spectrum of ionized gases is developed and the spectrum of He gas under electric and magnetic fields are studied. The results are shown through captured photographs, which shows that the ...
Generation of supersonic solitions by earthquake emission in the van Allen rediation belt
(BRAC University, 2005)
The parametric coupling between earthquake emitted circularly polarized electromagnetic radiation and ponderomotively driven ion-acoustic perturbations in the Van Allen Radiation Belt is considered. A cubic nonlinear ...
